Hospitology Products Mattress Encasement – Zippered, Waterproof, Dust Mite Proof Twin XL

Turn your bed into a quiet, protected sleep space with the Hospitology Mattress Encasement. Built for Twin XL mattresses (38" x 80"), it features an ultra low profile that works with mattresses from 6" to 8" deep, thanks to a flexible zipper and stretchable knit that stay taut without bulk. This layer is designed to feel almost invisible while providing serious protection during nightly use.

Protection you can feel

The encasement forms a 100% waterproof barrier on all six sides, and it has been lab tested to ensure durability. A built-in bed bug and dust mite barrier helps maintain a clean, dry sleeping surface, while the breathable design keeps air moving to reduce heat and humidity buildup.
